WHAT YOU NEED TO KNOW ABOUT CELL PHONE HARDWARE REPAIR AND SERVICES
The cell phone is a minicomputer with hardware and software components that are interdependent, any of them can be the cause of a fault. You need to identify the source of the problem, any visible component you can feel or touch is called the hardware while software is set of instructions or programmes that allow your handset perform specific functions or task. A good interpretation of the functions you are carrying out is done by the software. Hardware and software are mutually interdependent; one cannot function without the other, malfunctioning of either or both renders the phone useless.
A good technician must understand how the system operates to be effective in carrying out corrective operation on cell phones. When a cell phone is switched on the first thing it does is to check if the SIM card is inserted, followed by its acceptability. If the SIM card is accepted, the cell phone will undergo self -test operation, then booting to service mode for it to transmit and receive calls perfectly.

Malfunctioning of any of the three major areas of PCB-power, audio and RF sections renders the cell phone useless, and steps should be taken to rectify the fault.
